Abstract

The paper discusses modelling of water droplet heating and evaporation in dry air at different initial temperature. The effect of black body spectral radiation of air temperature to combined heat transfer in the semitransparent droplet has been evaluated. The effect of sprayed water temperature has been highlighted. Influence of water initial temperature to droplet heat and mass transfer during unsteady evaporation regime was evaluated by ratio of water initial and droplet equilibrium evaporation temperatures.
